Upgrade to OpenSearch® 3.3.2

OpenSearch® version 3.3.2 is now available for Aiven for OpenSearch services. Apply this version on your services to benefit from the major upgrade to version 3, which brings significant performance improvements, a modernized user experience, and powerful new capabilities, especially in observability and AI/ML-driven search.

Highlights

  • OpenSearch Dashboards - redesigned experience
    • Unified observability experience (preview): A redesigned Discover interface in OpenSearch Dashboards brings log analytics and distributed tracing together, offering an all-in-one view for troubleshooting and monitoring. To ensure service stability, the new Discover experience is disabled by default while in beta for version 3.3. We plan to enable this by default once it reaches general availability (GA) in a future release. To enable this feature before its GA, contact your account manager.
    • Smarter visualizations: New features enable smarter, automated visualizations and more chart types, making data analysis faster and insights easier to obtain.
    • Discover traces: A dedicated, central interface for querying and exploring traces across your distributed systems.
  • Enhanced performance and core search
    • Lucene 10 upgrade (since v3.0): This core upgrade modernizes the search infrastructure, leading to improved indexing and search performance, and better efficiency.
    • Better hybrid search: Enhancements like Z-score normalization for result scoring provide more accurate and relevant results when combining different search methods.
    • Star-tree indexing improvements: Speeds up slow-running aggregations, particularly multi-terms aggregations, for large datasets.
  • Powerful analytics with piped processing language (PPL)
    • Apache Calcite integration (since v3.0): PPL now uses the Apache Calcite query engine by default, introducing better portability, optimization capabilities, and an extensive library of new PPL functions for data manipulation and analysis.
    • New PPL commands: Introduction of commands like timechart for time-series aggregation and enhanced functions like coalesce and mvjoin for complex data transformations.
  • Vector search enhancements: Continued improvements to vector search, including the new Seismic sparse retrieval algorithm for faster neural sparse search, supporting more sophisticated generative AI and semantic search applications.
